Released Rector 2.6.5

Caching

This release makes the cache smarter about config changes - fewer needless full re-runs, while still invalidating when results could actually differ.

Configured rule value changes now invalidate the cache (#8400)

withConfiguredRule() stored its config on the RectorConfig instance only, never in the cache hash. Changing a rule's values - same class, different config - kept serving the stale result.

 return RectorConfig::configure()
     ->withConfiguredRule(SomeRector::class, [
-        'old value',
+        'new value',
     ]);

Before: cache kept, files re-analysed with stale value. After: cache dropped, re-analysed with new value. Merged config now flows through a RULE_CONFIGURATIONS parameter into the strict cache hash. Upgrading invalidates the cache once for projects using configured rules.

--only <Rule> reuses the full-run cache (#8400)

Each --only selection has its own cache namespace, so a file left clean by a prior full run was re-analysed under --only even when nothing changed. A scoped run now falls back to the full-run cache (read only, file content still compared, so real edits are still picked up).

vendor/bin/rector process       # full run, files left clean are cached
vendor/bin/rector process --only "Rector\..\SomeRector"

Before: --only re-analyses every file. After: skips files the full run already left clean.

Directional cache invalidation on config change (#8397)

Previously any change to any config parameter dropped the whole cache. Now changes are compared by direction:

• removing a rule/set, or adding a skip -> strictly less work -> cache kept
• adding a rule/set, or removing a skip -> more work possible -> cache dropped
• output-affecting params (php version, import names, indent) -> any change still drops the cache
• runtime/reporting params (--parallel, memory limit, deprecation notices) -> never invalidate

 return RectorConfig::configure()
     ->withRules([
         SomeRector::class,
-        OtherRector::class,     // removing a rule -> cache kept
     ]);

 return RectorConfig::configure()
     ->withSkip([
         SomeRector::class,
+        AnotherRector::class,   // adding a skip -> cache kept
     ]);

Before: full cache dropped, every file re-analysed. After: cache kept, only changed files re-analysed. A legacy cache value from an older version triggers a single safe reset.
